1. Check NSH_NETINIT for self network initialization 2. Check NSH_ARCHINIT for sel arch specific initialization 3. Always show help regardless of NSH_BUILTIN_APPS 4. Loop forever regardless of NSH_BUILTIN_APPS, user could: a.change the default behavior by the command line argument b.or ctrl+c to break out the loop

/* This test depends on these specific CAN configurations settings (your

|
* specific CAN settings might require additional settings).
|
|
*
|
|
* CONFIG_CAN - Enables CAN support.
|
|
* CONFIG_CAN_LOOPBACK - A CAN driver may or may not support a loopback
|
|
* mode for testing. The STM32 CAN driver does support loopback mode.
|
|
*
|
|
* Specific configuration options for this example include:
|
|
*
|
|
* CONFIG_CAN_LOOPBACK
|
|
* CONFIG_EXAMPLES_CAN_DEVPATH - The path to the CAN device. Default: /dev/can0
|
|
* CONFIG_EXAMPLES_CAN_NMSGS - This number of CAN message is collected and
|
|
* the program terminates. Default: 32.
|
|
* CONFIG_EXAMPLES_CAN_READ - Only receive messages
|
|
* CONFIG_EXAMPLES_CAN_WRITE - Only send messages
|
|
* CONFIG_EXAMPLES_CAN_READWRITE - Receive and send messages
